Purpose: To study the effect of orbital steroid injections administered in the treatment of thyroid eye disease (TED) on intraocular pressure (IOP). Methods: Retrospective chart review of consecutive patients over 70 months with active thyroid eye disease (TED) seen in a referral oculoplastic practice who underwent orbital steroid injections. Results: The clinical records of 56 patients were in...

The most favored model of humidity transduction views the cuticular wall of insect hygroreceptive sensilla as a hygromechanical transducer. Hygroscopic swelling or shrinking alters the geometry of the wall, deforming the dendritic membranes of the moist and dry cells. The small size the sensilla and their position surrounded by elevated structures creates technical difficulties to mechanically ...

i ntroduction: our study was designed to assess the effect of the submucosal injection of dexamethasone on postoperative discomfort after surgical removal of impacted mandibular third molars. m at erials and methods : twenty six patients with bilaterally bony impacted mandibular third molars were recruited to this split mouth study. on the study side, prior to surgery, 8 mg of dexamethasone was...

Abstract Faults/weakness zones with gouge containing swelling clay (smectite) have in several cases caused serious stability problems tunnels. The first part of this paper describes briefly some recent instability/cave-in where has been a main cause the incident, followed by brief reviews structure and properties smectite relevant laboratory test procedures. Main focus is placed on pressure, wh...

BACKGROUND Coma is a frequent presentation of severe malaria in adults and an important cause of death. The role of cerebral swelling in its pathogenesis, and the possible benefit of intravenous mannitol therapy to treat this, is uncertain. METHODS A computed tomographic (CT) scan of the cerebrum and lumbar puncture with measurement of cerebrospinal fluid (CSF) pressure were performed on admi...

A novel polypeptide hydrogel has been synthesized by crosslinking poly(L-glutamic acid) (PLG) with poly(ethylene glycol) (PEG). The PLG-PEG hydrogel was shown to be highly hydrophilic, and the extent of swelling varied with pH, increasing at higher ionization of the PLG. Aside from electrostatic effects, such as ion-ion repulsion and internal ion osmotic pressure, circular dichroism studies sho...

The swelling behavior of fully neutralized sodium polyacrylate gels was investigated in aqueous solutions of alkali metal (LiCl, NaCl, KCl, CsCl) and alkaline earth metal salts (CaCl2, SrCl2, BaCl2). The total salt concentration and the ratio of monovalent to divalent cations were varied in the biologically significant range. It is found that the concentrations of both monovalent and divalent c...

BACKGROUND Case fatality rates among African children with cerebral malaria remain in the range of 15 to 25%. The key pathogenetic processes and causes of death are unknown, but a combination of clinical observations and pathological findings suggests that increased brain volume leading to raised intracranial pressure may play a role. Magnetic resonance imaging (MRI) became available in Malawi ...

Seven patients with intracranial disorders were studied during recovery from anaesthesia with nitrous oxide and halothane. Arterial, intracranial, and central venous pressure, and arterial carbon dioxide tension were measured and compared with the patient's clinical state. No patient had evidence of increased brain volume when the dura was closed. All had been hyperventilated during the surgica...
